Spent thousands of coins on getting 10 boosts, not credited to my account however during play the game asks me to renew my boosts using 40 gems? If I don't have gems it uses my coins which is much preferable so my question are: Is this game a rip off? Why doesn't it credit your boosts when you buy them? Why does it use your gems just because you have them available when if you don't have gems it's quite happy using coins to replenish boosts? All these questions, not to mention when you are "unable to join game" but it still takes your tickets!!! Please sort this out Sharkparty.
